To allwlwm 'it may concem:

Be it known that I, Orro PoRBnoK, a citizen of the United States,residing at St. Lou1s,'Missouri, have invented a certain new and usefulImprovement in Dust Collectors and Separators, of which the following isa. full, clear, and exact description, such as will enable othersskilled in the art to which itappertains to make and use the same,reference being had to the accompanying drawmgs, forming part of thisspecification, in which- Figure 1 is an elevationalv view partly invertical section of a dust collector and separator constructed inaccordance with my invention; Fig. 2 is an enlarged cross sectional viewtaken on approximately the line 2 -2 of Fig. 1; Fig. 3 is an enlargedcross sectional view taken on approximately the line 3-3 of Fig. 1; Fig.4 is a perspective view of one of the pieces from which the dust-'collecting chamber is formed; Fig. 5 is a perspective view of one of thesections of the ring that is inter osed between the lower end of thedust-co lecting chamber and the casing arranged underneath-same; Fig. 6is a perspective view of one of the gussetshaped pieces from which thescreen casing is formed; and Fig. 7 is a perspective view of one sectionof the top of the dust-collecting chamber.

This invention relates to dust collectors and separators.

The main object of my invention is to provide a dust collector andseparator which is so constructed that it can be shi ped in knock-downshape from the manui acturer to the purchaser and erected by him withoutthe aid of a skilled mechanic, thereby reducing greatly the cost oftransportation owing to the fact that the device occupies very littlespace in its knock-down form.

Another object of my invention is to provide a dust collector andseparator that is composed of a number of parts which are detachablyconnected together so that when one part becomes damaged or wears out itcan be replaced by a new part. Other objects and desirable features ofmy invention will be hereinafter pointed out.

Referring to'the drawings which illustrate the preferred form of myinvention, A designates a cylindrical-shaped dust-collecting chamberinto which the feed pipe B 1 projects, and C designates an invertedconical-shaped casing arranged underneath the of the casing (J andatfthe lower end of the screen I), as shown in Fig. 1.

Prior to my invention the cylindrical-.

shaped member that formedv the dust-collecting chamber of a separatorand the inverted conical-shaped casing arranged underneath same werebuilt complete by the manufacturer and shipped to the purchaser. Asthese parts occupied a great deal of space the freight rate on same washigh and, furthermore, they were very apt to become bent or damaged intransit.

The main object of my invention is to provide a separator that can beshipped in knock-down form so that it will occupy very little space, andto this end I have devised a separator in which the cylindricalshapedmember A, the casing (J and the screen D are composed of a plurality ofparts that the manufacturer can ship in knock-down form and which can beassembled or connected together by the purchaser without the aid of askilled mechanic.

The member A which forms the dust-collecting chamber is composed of anumber of pieces 1 of sheet metal, each of which is provided on one ofits longitudinal edges with an outwardly projecting flange 2 and on itsother longitudinal edge with an outwardly projecting channel-shapedportion 3 that is adapted toreceive the flange 2 of an adja cent piece 1when the pieces 1 are assembled, as shown in Fig. 3. The pieces 1 arecurved slightly so that they will form a cylindricalshaped member whenthey are assembled, and each piece is provided at its lower end with aninwardly projecting flange 4 and a pair of wings 5 that projectlaterally beyond the marginal edges of the piece, as shown in Fig. 4.The cooperating flanges 2 and channel-shaped portions 3 of the pieces 1can be connected together after they have been assembled by any suitablefastening devices, such, for example, as bolts 6, as shown in Fig. 2,and the wings 5 at the lower ends of the pieces 1 are also preferablyconnected to the adjacent pieces with which they contact so as toproduce a very rigid structure.

The top of the member A is preferably composed of two semi-ring-shapedsections, each of which consists of a piece of wood 7 e the twosections.

' tion, the discharge spout E of the casing O After the sections havebeen assembled they are connected together by bolts or other suitablefastening devices 10 that pass through the inverted channel-shapedportion 11 and the flange 10 of the top plates of The air pipe G,through which the air escapes from the dust-collecting chamber A, isprovided at its lower end with a laterally projecting flange 13 that canbe connected to the top of said chamber by means of fastening devicesthat pass through said flange.

The inverted conical shaped casing C which is arranged underneath themember A is composed of a number of gusset-shaped pieces 14, each ofwhich is provided on one of its edges with an outwardly projectingflange 2 and on its other longitudinal edge with an outwardly projectingchannelshaped portion 3 that is adapted to receive the flange 2 of anadjacent piece 14 when said pieces are assembled, said pieces beingconnected together by bolts or suitable fastening devices 6" that passthrough said flanges and channel-shaped portions. Each of thegusset-shaped pieces 14 is provided at its lower end with a pair oflaterally projecting wings 5 and when said pieces are assembled one ofsaid wings projects over one of the adjacent pieces 14 and the otherwing projects under the other adjacent piece 14, said wings beingprovided with openings 15 through which bolts or other suitablefastening cfices 16 pass to connect the wings of the various piecestogether, as shown in Fig. 2. A flanged ring 17 is arranged at the lowerend of the casing C and the bolts 16 that pass through the wings 5 ofthe pieces that constitute said casing, also pass through the flange ofsaid ring to retain it in posibeing connected to the ring 17, as shownin Fig. l.

The upper edge of the casing C and the lower edge of the member A areconnected together by means of a wooden ring H that is composed of anumber of segmentalshaped sections 18, as shown in Fig. 5, each of saidsections being provided with a top plate 19 that laps over the end of anadjacent section and is secured thereto by suitable fastening devices.The outer edge of this ring H is beveled slightly so as to conform tothe inner face of the casing C and the plates 19 on the top side of saidring pro- I ject laterally over the upper edge of the easing C, as shownin Fig. 1, the casing C being connected to the ring H by any suitablefastening devices. The lower end of the member A projects into the ringH and is secured tihereto by fastening devices, as shown in The screen Dis also composed of a number of gusset-shaped pieces 20 of the sameconstruction as the pieces 14 which form the casing O, the screen piecesbeing provided with cooperating flanges 2 and channelshaped portions 3and also laterally projecting wings 5 through which fastening devices 16pass. The discharge pipe F which is arranged at the lower end of thescreen I) is provided with a flared flange into which the lower end ofthe screen pro ects and this discharge pipe projects laterally throughan opening in the discharge pipe E, as shown in Fig. 1, the upper edgeof the screen D being interposed between the inner face of the ring IIand the inwardly projecting flanges 4 on the pieces 1 which constitutethe member A.

The pieces which constitute the member A, casing C, screen D, ring H,and top of the member A, are not connected together when themanufacturer ships them to the urchaser so that the device occupies verylittle space and therefore can be shipped at a low freightclassification. When the purchaser receives the device he can erect itquickly and without the aid of a skilled mechanic- Having thus describedmy mvention, what I claim as new and desire to secure by Letters Patentis:
